Sinking ships in port

By experience I have found that as soon as I start sinking ships at port a number of unwanted side-effects WILL occur soon thereafter.

1. Strange external camera behavior.
I do have TMO installed enabled but I re-enabled the external cam. The cam fails to focus on any target whatsoever and returns errors like "out of sector" at all sorts of weird angles.

2. Performance degradation.
Especially noticeable during time compression >x1024. Frame rate gets choppy.

3. Strange behavior upon loading a game.
Whenever one or more of the above has already occurred and a game is saved and reloaded the game immediately applies what seems to be random damage to one or more (sub)systems. The damage can be repaired.

4. Crashes.
When I continue the patrol despite above errors the game also starts to crash at changing camera views (like pericope to bioculars). Memory leaks also seem to occur according to the task manager. At around 1.6Gig the game reliably crashes. Enabling LAA flag in the .exe does not seem to avoid this crash.

After ending a patrol the above seems to reliably fix itself. I can reliably replicate any and all of the above behaviors at any point during the pacific campaign. Sinking a few stationary ships at port is all it takes.

So now I don't sink ships at port anymore and it's not a big deal. This post is to inform those with similar game behavior what the cause may be.
